Interesting thread. I wonder if Boeing will come up with a 757-X or similar in the future? Think about it - lots of airlines are now doing or have talked about point to point crossings across the pond with 757's from places like MAN, BRS, LPL, NCL etc. There's not enough demand to fill a 767, 777 or A330on these routes and the 757 is the only one for the job. As these aircraft are retired, they'll be impossible to replace with anything currently in existence.
